A Simple Resolver-to-DC Converter

A full-range-360° resolver-to-DC converter

“…In the past, the converter methods based on phase-locked loop technique [1][2] or look-up table technique [3]. Alternatively, the new design of resolver-to-DC converter without a processor and/or look-up table technique has been described [4][5]. However, the approach in [4] has complex structure in inverse-sine function circuit.…”

“…However, the approach in [4] has complex structure in inverse-sine function circuit. The simple configuration can be obtained in [5]. Unfortunately, this approach has some errors occurred in the main component in inverse-sine function used for converting operation.…”
